(54) System and method of a stereo receiving system


(57) A system (10) and method (50) of a stereo receiving system, including a plurality of antennas, a receiving device (16), a plurality of summing devices, a phase lock loop device (46), a controllable phase shifter device (38), and a gain-control device (18). The plurality of antennas receive RF signals having a common frequency but potentially different phases. The receiving device (16) is in electrical communication with the plurality of antennas. The plurality of summing devices are in electrical communication between at least one of the plurality of antennas and the receiving device (16). The phase lock loop device (46) is in electrical communication with the receiving device (16). The gain-control device (18) is in electrical communication between the plurality of antennas and the receiving device (16), wherein the gain-control device (18) controls a signal-to-noise ratio of the RF signals aligned from the plurality of antennas.
